Description

Portable burner

The present invention relates to a portable burner, and more particularly to a portable burner that allows a user to visually inspect fuel.

With the recent increase in camping activities, portable burners for cooking are being used in large numbers.

Such portable burners are classified into a gas burner using a gas and an oil burner using oil. To this end, the portable burner additionally has a fuel storage unit for storing gas or oil.

Typically, the fuel storage unit is formed to be opaque. For example, the fuel storage unit is formed of plastic, metal, or the like of an opaque color. This may make it difficult for the user to visually observe the inside of the fuel storage unit.

In order to check the amount of fuel (gas or oil) remaining in the fuel storage unit when using the portable burner, the user should separate the fuel storage unit from the portable burner. For the convenience of the user, a portable burner capable of visually checking the amount of fuel remaining in the fuel storage unit is required.

Accordingly, one aspect of the detailed description is to provide a portable burner capable of visually inspecting the amount of fuel remaining in a fuel storage unit.

Another aspect of the detailed description is to provide a portable burner that minimizes damage and deformation.

To achieve these and other advantages, and in accordance with the purpose of the present specification, as embodied and broadly described herein, a portable combustor including a combustor body and a fuel storage unit is provided; the combustor body includes a combustor head; fuel A storage unit is disposed below the burner body and configured to supply fuel to the burner head. Wherein the fuel storage unit includes an inner casing and an outer casing; the inner casing is configured to store fuel; and the outer casing is configured to receive the inner casing therein. Wherein at least a portion of the inner and outer casings are formed to be transparent or translucent, and wherein a damper is formed between the inner and outer casings.

In this configuration, the user can visually check the amount of fuel remaining in the fuel storage unit and minimize damage and deformation of the portable burner.

The invention can have the following advantages:

First, since the fuel storage unit for supplying fuel to the burner head is formed to be transparent or translucent, the amount of fuel remaining in the fuel storage unit can be easily checked when the portable burner is used.

Secondly, since the damper is formed between the inner casing and the outer casing of the fuel storage unit, the impact applied from the outside to the portable burner can be buffered. This can prevent damage and deformation of the fuel storage unit.

Description of the exemplary embodiments will now be given in detail with reference to the drawings. For the sake of brief description with reference to the drawings, the same or equivalent elements will have the same element symbols, and the description thereof will not be repeated.

A preferred embodiment of the present invention will be explained in more detail hereinafter with reference to Figures 1 to 4.

1 is a perspective view of a portable burner according to an embodiment of the present invention; FIG. 2 is a perspective view of the fuel storage unit of FIG. 1; and FIG. 3 is a cross-sectional view taken along line "III-III" of FIG. 2; 4 is a perspective view of the back side of the fuel storage unit of FIG. 2.

1 to 4, a portable combustor 10 according to an embodiment of the present invention includes a combustor body 100 and a fuel storage unit 200; the combustor body 100 includes a combustor head 140; and the fuel storage unit 200 is disposed at the combustor Below the body 100 and configured to supply fuel to the burner head 140.

The burner body 100 also includes a food storage unit 120 configured to store food therein. Alternatively, the combustor body 100 can also include a food storage unit 120 and a handle 130 that is configured to facilitate use of the food storage unit 120 and to facilitate separation of the food storage unit 120 from the burner head 140.

The fuel storage unit 200 is a member configured to store fuel to supply fuel to the burner head 140. The fuel storage unit 200 includes an inner housing 220 and an outer housing 230; the inner housing 220 is configured to store fuel; the outer housing 230 is configured to receive the inner housing 220 therein. At least a portion of the inner casing 220 and the outer casing 230 are formed to be transparent or translucent. The damper 250 may be formed between the inner casing 220 and the outer casing 230.

More specifically, the outer casing 230 may be implemented as an appearance of the fuel storage unit 200 and may be formed to have the same shape and size as the burner head 140. The support 232 may be further formed at the outer casing 230, and the support 232 is configured to support the fuel storage unit 200. The support 232 may be integrally formed with the outer casing 230.

A storage tank 222 may be formed at the inner casing 220, and the storage tank 222 is configured to store fuel therein. The storage tank 222 may be formed in a doughnut shape in which both ends are spaced apart from each other. The reason is as follows: A spiral coupling unit 240 (which will be explained later) formed of a metal material can be mounted to a central region of the inner casing 220. The spiral coupling unit 240 can increase the heat diffusion of the fuel stored in the inner casing 220.

The fuel stored in the inner casing 220 may be oil or gas. Hereinafter, the present invention will be explained on the assumption that gas is stored as fuel in the inner casing 220. However, the present invention is not limited by the type of fuel stored in the inner casing 220.

The inner casing 220 and the outer casing 230 may be formed to be transparent or translucent. For example, the inner casing 220 and the outer casing 230 may be formed of a transparent plastic material, an anthrone, a ruthenium rubber, or the like. The user can check the degree of fuel reduction by visually checking the amount of fuel stored in the inner casing 220. This can make it easier to fill the fuel or replace the fuel storage unit 200 depending on the amount of fuel remaining.

The inner housing 220 and the outer housing 230 may be formed to be spaced apart from each other by a gap defined by the damper 250. The reason is as follows: When the fuel stored in the inner casing 220 is heated, the temperature of the inner casing 220 rises. The elevated temperature can be transferred to the outer casing 230, which can damage or deform the outer casing 230. In order to solve such damage of the outer casing 230, the inner casing 220 and the outer casing 230 are formed to be spaced apart from each other by a prescribed gap. In this configuration, it is possible to prevent the high temperature generated when the fuel stored in the inner casing 220 from being heated is directly transmitted to the outer casing 230. Therefore, damage and deformation of the outer casing 230 can be prevented.

The damper 250 includes a plurality of ribs 252 between the inner housing 220 and the outer housing 230. The rib 252 may be formed at a gap between the inner casing 220 and the outer casing 230. The ribs 252 serve to cushion the impact applied to the portable burner 10. Portable burners 10 commonly used outdoors may be easily damaged by external impact. However, since the rib 252 buffers the impact applied to the portable burner 10, the portable burner 10 can be prevented from being damaged.

The ribs 252 can increase the cushioning force by being arranged in the form of diagonal lines. For example, the ribs 252 may be formed to be inclined in a clockwise direction. However, the invention is not limited thereto. That is, the rib 252 may be formed to be inclined in the counterclockwise direction.

The fuel storage unit 200 is explained in more detail. The inner casing 220 may be formed in a ring shape in which both ends are spaced apart from each other. The reason is because the lower end of the burner head 140 is mounted to the inner casing 220 along the outer circumference of the storage tank 222. The inner casing 220 also includes a spiral coupling unit 240 formed of a metal material. The helical coupling unit 240 has a plurality of helical openings 244 for connection with a plurality of bolts 50 such that the burner head 140 whose lower end has been mounted to the inner casing 220 is supported. The spiral coupling unit 240 may be formed to surround the end of the bolt 50 that has been inserted into the screw opening 244, thereby preventing the bolt 50 from directly contacting the inner casing 220 when the portable burner 20 is operated.

The spiral opening 244 may be formed penetratingly at the outer casing 230 and the inner casing 220 such that the outer casing 230 and the inner casing 220 may be simultaneously assembled to each other by the bolts 50 that have been inserted into the spiral openings 244.

The helical coupling unit 240 further includes an extension plate 242 that extends from the end of the helical coupling unit 240 toward the sidewall of the inner casing 220 and that is configured to accelerate combustion of fuel stored in the inner casing 220. That is, the helical coupling unit 240 and the extension plate 242 can prevent the burner head 140 and the inner casing 220 from melting due to the fuel stored in the inner casing 220 due to the inner casing 220 and the burner head 140. It is heated by direct contact. When the fuel stored in the inner casing 220 is heated, since the temperature of the spiral coupling unit 240 and the extension plate 242 rises, it is possible to accelerate the volatilization of the fuel stored in the inner casing 220.

The outer housing 230 may also include a plurality of bolt insertion openings 234 that extend from the outer housing 230 and are formed to surround the bolts 50 that are coupled to the spiral openings 244. The bolt insertion opening 234 is formed to have a diameter larger than the diameter of the spiral opening 244 so as not to contact the outer surface of the bolt 50.

The bolt insertion opening 234, that is, the insertion hole for inserting the bolt 50, is formed to have a diameter larger than the diameter of the bolt 50. In this configuration, the bolt 50 can be prevented from adhering to the outer casing 230 and the inner casing 220, which is caused by the casing being melted due to the high temperature when the portable burner 10 is operated.

The inner housing 220 also includes an inner housing body 223 and a cover 210; the inner housing body 223 has an open upper end 225; the cover 210 is configured to seal the upper end 225 of the inner housing body 223. The cover 210 may be formed of a transparent or translucent material. Preferably, the cover 210 may be formed of the same material as the inner housing 220 and the outer housing 230.

More specifically, the cover 210 includes a coupling groove 212 that is formed to surround the upper end 225 of the inner housing body 223. When the upper end of the inner casing 220 is properly mounted to the coupling groove 212, the coupling groove 212 is configured to seal the fuel stored in the inner casing 220. The coupling groove 212 is formed to have a size smaller than the size of the upper end of the inner casing 220. In this configuration, when the upper end of the inner casing 220 is properly mounted to the coupling groove 212, the upper end of the inner casing 220 is prevented from being separated from the coupling groove 212.

The upper end 225 of the inner casing body 223 may be formed such that its thickness may decrease toward the upper side. In this configuration, the upper end 225 of the inner casing body 223 can be easily coupled to the coupling groove 212, and the degree of sealing between the upper end 225 of the inner casing body 223 and the coupling groove 212 can be improved.

The cover 210 and the inner housing body 223 may be welded to each other. More specifically, the sides of the cover 210 and the inner casing main body 223 can be welded to each other by using ultrasonic waves. When the sides of the cover 210 and the inner casing main body 223 are welded to each other, the fuel stored in the inner casing 220 can be prevented from leaking. Moreover, resistance to pressure applied to the inner casing 220 can be enhanced when the fuel stored in the inner casing 220 is burned.

That is, the inner housing 220 further includes a package 224 attached to the cover 210 at the upper end 225 of the inner housing body 223. When the upper end of the inner casing 220 is properly coupled to the coupling groove 212, the package 224 may be attached to the cover 210, thereby preventing the upper end of the inner casing 220 from being separated from the coupling groove 212. If the side of the inner casing main body 223 and the cover 210 are welded to each other by using ultrasonic waves, the package 224 is pressed into the cover 210. Therefore, the degree of adhesion between the cover 210 and the upper end 225 of the inner casing main body 223 is increased. Therefore, the inner casing 220 is further sealed, so that the fuel stored in the inner casing 220 can be prevented from leaking.

When the cover 210 is disposed at the upper end 225 of the inner casing main body 223, the upper portion of the inner casing 220 is sealed, so that leakage of fuel can be prevented. Moreover, when the side surface of the inner casing main body 223 and the cover 210 are welded to each other by using ultrasonic waves, the gap between the package 224 and the cover 210 provided at the upper end 225 of the inner casing main body 223 is compressed. Therefore, the inner casing 220 is secondarily sealed, thereby additionally preventing fuel leakage.

Before the inner casing 223 and the cover 210 are welded to each other, the package 224 is coupled to the coupling groove 212, thereby attaching the inner casing body 223 and the cover 210 to each other. A package 224 formed of a rubber material may additionally be mounted to the upper end of the inner casing 220. Alternatively, the upper end of the inner casing 220 may be formed to have a spherical shape such that the upper end of the inner casing 220 may function as the package 224.

The fuel storage unit 200 mounted to the portable burner 10 is formed to be transparent or translucent. Therefore, when the portable burner 10 is operated, the degree of increase or decrease in fuel can be visually checked. This may enable the filling of the fuel or the replacement of the fuel storage unit 200 to be performed at a more appropriate time.

The above embodiments and advantages are merely exemplary and are not to be considered as limiting. The present teachings can be readily applied to other types of devices. The description is intended to be illustrative, and not to limit the scope of the invention. Many alternatives, modifications, and variations will be apparent to those skilled in the art.
